/* ==========================================================================
   MTC Tennis — Component Library
   Phase 1A: Namespaced component classes only. No visual changes.

   All classes use the .mtc- prefix. None of these classes are referenced
   by current markup — they are ready for Phase 2 section-by-section
   migration.

   IMPORTANT: This file does NOT define or override broad selectors like
   .btn, .card, .form-control, .alert, .modal, etc.
